What kind of display are you using and at what resolution do you game at? I would reccomend a 7950 over a 7970 for a single monitor setup at resolutions at or lower then 1920x1200. I would not suggest 560ti's in sli right now you can get good performance with a single card solution and then if you want to add another 7950 in your rig later on. A 7950 can be had for under 400 euro's so you can put that extra money towards a better PSU. This may be a personal thing but I have not had good experiences with cooler master products and I think you would be better off with a XFX or Corsair 1050w.
